    Not an optical illusion, they are not perpendicular to center line
    I think that is called a skew bevel

    So if the location is set by the worn bearings about to be replaced, and drive is through the pinon gear along the outside, what is the large vertical shaft with with the cone for?

    To keep it vertical, without it the table would rock around with the load upon it.

    Got the bearing race off the table yesterday. Did not come off easy.

    Did it come off as one piece? I do see now how it looks like two steel rings that held down the bearing.

    When you think you have the bearings back in useable shape, I would certainly plan on bluing up the ring and pinion and checking the tooth contact pattern before you put it back under power. Best of luck with the repair!

    Jayzus. I don't like to even use "12-point" sockets. At all.

    Hex, four, or eight-point, rather. And both generations of Torx "etc".
    Only a few "Penta" though. Water-meter boxes. Jaguar electric parking brakes...

    It comes off in one piece. The bearing is off in the 2nd picture, just sitting on top of the fit before it was lifted off.

    Kinda hard to control an impact wrench. Used the two jack bolts to lift it out of the fit, and put dial indicators next to the jack bolts to raise the bearing up evenly, so every turn was measured.

    The fit was so tight, that the bearing started going potato chip between the jack bolt holes as it was getting hung up. All the air lines were running air hammers hitting the back side of the chuck to vibrate the fit and help the bearing out.

    Took 4 guys on air hammers and 2 guys on wrenches 5hrs to get it out.

    For sure.

    We build centrifugal geared compressors (and literally all other types of rotating equipment) all the time and have lots of ways to check gear contact.

    Was supposed to work today. But got the day off.

    Moved this gantry crane into the shop. A little sketchy, lifting with the actual mast not forks. But worked well.

    Gotta add some more bracing and bolts. Then going to be taking the boom off my F800 to reaseal the extension cylinders.

    Since we finally have dried out here in texas after 2 weeks of rain.

    Moved lots of junk out of the pasture with this forklift that's finally sort of working.

    Also solved my caster problem on the crane. Actual casters to support the weight I wanted were aboit $ 1k each.

    These 8ton machinery skates were roughly 75 bucks each.

    Going to make some "pucks" to weld to the bottom of the legs so the skates couldn't slide out. But can also be easily removed for using the skates for rigging.

    Going to make some heavy jack bolts to go on each side to act as out riggers for heavy lifts or to lift up the gantry to reposition the skates

    Going fine. One bearing has been re machined. Its in a mill rn, having extra lube lines added to it.

    Second bearing is at vendor to be re machined.

    Once the extra holes are added, going to shim the bottom of this bearing (made an educated guess on how much more height i need), build out lube system, wait for 2nd bearing to be recut. Install 2nd bearing in the chuck, the install the table. Check the gear contact. Then have an actual shim waterjetted and ground to a specific thickness that'll be determined based on gear contact.

    Thought yall might like to see this. Old compressor we are starting to overhaul. Lots of work on this machine.

    Was built new in 1944, and the split line was cut originally on a giant planer. Still shows the tool marks

    Big case, 90" diameter internal fits, but light. Only 14,350lbs.

    Like many machine castings from The War, it could use some bondo in places....

    So, is that from a 16-71?

    i would think you'd need more numbers in front of that '71'

    Nothing goofy about that set up, Matt. I've done similar more than once. Would have been easier if my HBM had a built in rotary table.

    So, the King will be back in operation next week?
